This was my thinking. I've had two days of training with Howard and it is going to be at least a few months before I get a chance to train with him again. I was just curious as to whether "generically" Tai Chi would get my body moving in a better way.

you could do a search for folks in your city who teach Chen style taiji and check them out. check to see if they focus on zhan zhuang (standing post) and silk reeling or not. if they focus on doing the forms, then you can skip. the good one will make you do standing post until your legs fell off, then having you doing silk reeling until your body fell off. it's not pleasant.
